1206Y1000102MSTE03

Overview

The Knowles Syfer 1206Y1000102MSTE03 is a Surface Mount Multilayer Ceramic Capacitor (MLCC) featuring X7R dielectric characteristics. It offers a capacitance of 1000 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes the FlexiCap termination technology, providing enhanced mechanical reliability for board-flex sensitive applications. It is qualified to AEC-Q200 standards for automotive use and operates within a temperature range of -55°C to +125°C.

Feature Summary

• FlexiCap flexible termination technology accommodates significant board bending without cracking
• AEC-Q200 qualification ensures reliability for automotive electronic environments
• X7R dielectric material provides stable capacitance performance across wide temperature ranges

Applications

• Automotive electronics requiring high mechanical reliability
• Board-flex sensitive circuit designs
• General purpose surface mount applications

Procurement Notes

Verify the specific suffix STE03 against official datasheets to confirm terminal configuration and barrier layer specifications. Ensure compatibility with assembly processes regarding the flexible termination material. Confirm availability status as supply may be restricted or subject to allocation. Cross-reference RoHS compliance documentation for regulatory adherence in target markets.

Selection Notes

Select this component when board flexing is a primary concern during operation or assembly. The X7R dielectric suits general coupling and decoupling needs where moderate stability is acceptable. Consider the 1206 footprint constraints and 100V rating requirements. Verify that the ±20% tolerance aligns with circuit design margins for noise filtering or timing applications.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed specifically to address mechanical failure modes in standard MLCCs. The series is recognized for superior performance under thermal cycling and mechanical stress compared to conventional terminations. It represents a specialized solution for high-reliability sectors including automotive and aerospace.

Replacement Considerations

Direct substitutes must match the 1206 package, 100V rating, X7R dielectric, and FlexiCap termination style. Generic X7R capacitors lack the flexible termination benefit and are not suitable replacements for flex-sensitive boards. Consult manufacturer cross-reference lists for verified equivalents.
